Method of selecting ultrasonic transducers and ultrasonic transducers selected by this method.

摘要

The subject of the invention is a method for selecting ultrasonic transducers used in non-destructive ultrasonic testing devices. The method consists in establishing, under determined conditions, the frequency spectrum of the transducers to be tested, in comparing this spectrum with a reference spectrum, and in selecting the transducers whose spectra are identical to the reference spectrum.
